Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77568, here are decompositions:
- 5 + 77563 = 77568
- 11 + 77557 = 77568
- 17 + 77551 = 77568
- 19 + 77549 = 77568
- 41 + 77527 = 77568
- 47 + 77521 = 77568
- 59 + 77509 = 77568
- 79 + 77489 = 77568
Showing the first eight; more decompositions exist.
